| DT bindings for the Renesas R-Car System Controller |
| |
| == System Controller Node == |
| |
| The R-Car System Controller provides power management for the CPU cores and |
| various coprocessors. |
| |
| Required properties: |
| - compatible: Must contain exactly one of the following: |
| - "renesas,r8a7779-sysc" (R-Car H1) |
| - "renesas,r8a7790-sysc" (R-Car H2) |
| - "renesas,r8a7791-sysc" (R-Car M2-W) |
| - "renesas,r8a7792-sysc" (R-Car V2H) |
| - "renesas,r8a7793-sysc" (R-Car M2-N) |
| - "renesas,r8a7794-sysc" (R-Car E2) |
| - "renesas,r8a7795-sysc" (R-Car H3) |
| - "renesas,r8a7796-sysc" (R-Car M3-W) |
| - reg: Address start and address range for the device. |
| - #power-domain-cells: Must be 1. |
| |
| |
| Example: |
| |
| sysc: system-controller@e6180000 { |
| compatible = "renesas,r8a7791-sysc"; |
| reg = <0 0xe6180000 0 0x0200>; |
| #power-domain-cells = <1>; |
| }; |
| |
| |
| == PM Domain Consumers == |
| |
| Devices residing in a power area must refer to that power area, as documented |
| by the generic PM domain bindings in |
| Documentation/devicetree/bindings/power/power_domain.txt. |
| |
| Required properties: |
| - power-domains: A phandle and symbolic PM domain specifier, as defined in |
| <dt-bindings/power/r8a77*-sysc.h>. |
| |
| |
| Example: |
| |
| L2_CA15: cache-controller@0 { |
| compatible = "cache"; |
| power-domains = <&sysc R8A7791_PD_CA15_SCU>; |
| cache-unified; |
| cache-level = <2>; |
| }; |
